sift-gateway

概述

Sift 充当 AI 代理与上游 MCP 服务器或 CLI 命令之间的中间层。它解决了工具输出的关键痛点，包括大上下文消耗、不一致的 API 响应、分页问题和敏感数据暴露。通过将完整有效负载存储为 SQLite 工件并返回紧凑引用或内联数据，Sift 根据基准测试将准确性从 33% 提高到 99%，同时将输入令牌减少 95.4%。该解决方案支持 MCP 客户端和 CLI 工作流程，具有统一的工件契约。

装完之后，这里有 5 个你可以让 AI 做的事：

• artifact

  Query stored tool artifacts with Python code

  试试:Query the stored artifact with Python code to find all pods in the 'kube-system' namespace试试:Run analysis over the entire pagination chain of artifacts试试:Extract specific fields from the stored JSON data using Python
• gateway.inspect_tool

  Get full documentation for a tool from the upstream server

  试试:Inspect the 'list_files' tool to see its full documentation试试:Get detailed information about the 'query_postgres' tool
• run

  Execute upstream tool/command and capture JSON output

  试试:Run 'kubectl get pods -A -o json' and store as an artifact试试:Execute the 'list_files' tool with specific parameters
• next_page

  Continue pagination from the previous artifact

  试试:Get the next page of results from the previous query试试:Continue paginating through the API response

说明：Tools were inferred from the MCP gateway functionality described in the README, particularly the sections on how Sift works with MCP tools and artifact querying. The exact MCP tool names aren't explicitly listed in the provided README excer
